1.
Synthesis and characterization of the intermediate of piperonal:3,4-methylenedioxymandelic acid
洋茉莉醛中间体3,4-亚甲二氧基苯乙醇酸的合成与表征
2.
The synthesis of piperonal by nitric acid partially substituted with oxygen was achieved,because oxygen could quickly oxidize nitric oxide,which was the product of nitric acid oxidative decarboxylation of 3,4-methylenedioxymandelic acid(DMA) to piperonal,to NO2 that reacted with H2O and formed HNO3 and HNO2 again.
在氧气气氛中,硝酸氧化脱羧3,4-亚甲二氧基苯乙醇酸(DMA)后生成的NO很快氧化为NO2,与水作用后生成HNO3和HNO2可以继续参与反应,从而实现了氧气部分替代硝酸氧化脱羧合成洋茉莉醛的过程。
